Tóm tắt

The dynamic reponse of a three-span Timoshenko beam resting on a cubic nonlinear viscoelastic foundation is investigated in this paper. A displacement-dependent cubic nonlinear viscoelastic foundation model with six independent foundation parameters is considered. The concentrated moving load is considered with various cases: Velocity of load assumed to be constant; Moving load as a uniform increasing or decreasing motion. The governing equations of motion are established and solved using the Newmark direct time integration method over the entire time domain. Based on the obtained solution of the governing equation, deflection of beam is determined. Numerical investigations are then conducted to evaluate the effects of the foundation, beam, and loading parameters on the dynamic response of the beam.
